Compounded rapamycin (sirolimus) is a prescription capsule used off-label at low, intermittent doses to support healthy aging. Rapamycin works by inhibiting mTOR, a central cellular pathway that senses nutrients and controls growth. Dialing mTOR down triggers autophagy, the body's cellular clean-up process, and mimics some of the effects of caloric restriction, one of the most studied approaches to extending healthspan.
Rapamycin is one of the most compelling molecules in longevity research: it consistently extends lifespan and improves age-related function across animal studies, and in people, low doses have been shown to improve immune response and reduce markers of skin aging while being well tolerated. Because its effects are dose-dependent, longevity-focused prescribers use a low, intermittent schedule (often once weekly) rather than the continuous high doses used in transplant medicine, which is exactly why compounding matters. We prepare rapamycin in the precise low strength your prescriber selects.
Rapamycin is FDA-approved for preventing organ-transplant rejection and for tuberous sclerosis, and its use for healthy aging is off-label and prescriber-directed. At the low, intermittent doses used for longevity it is generally well tolerated, and prescribers monitor for side effects such as mouth sores or changes in lipids that are more common at higher, continuous doses. Use it under a prescriber who can tailor the dose and monitoring to you. Every batch is pharmacist-compounded, quality-verified, and shipped nationwide. Prescription required.
Frequently asked questions
What is low-dose rapamycin used for?
Off-label support for healthy aging and longevity. Rapamycin inhibits the mTOR pathway, triggering autophagy and mimicking effects of caloric restriction.
How does rapamycin work for longevity?
It inhibits mTOR, a nutrient-sensing pathway. Turning it down promotes cellular clean-up (autophagy) and is linked in research to improved healthspan and immune function.
Why is the dose and schedule so important?
Longevity use relies on low, intermittent dosing (often weekly), which is well tolerated, unlike the high continuous doses used in transplant medicine. That precision is why it is compounded.
Is rapamycin FDA-approved?
Yes, for organ-transplant rejection and tuberous sclerosis. Its use for healthy aging is off-label and directed by your prescriber.
Are there side effects?
At low intermittent doses it is generally well tolerated. Prescribers monitor for effects like mouth sores or lipid changes, which are more common at higher continuous doses.
